Description

Die Erfindung betrifft eine Warneinrichtung insbesondere für Baustellen im Bereich einer untertägigen Schiene-, Hänge-, oder-Standbahn mit wenigstens einer optischen und/oder akustischen Anzeige.The invention relates to a warning device, in particular for construction sites in the area of an underground rail, hanging or standing track with at least one visual and / or acoustic display.

In untertägigen Strecken, die von Einschienenhängebahnen oder Schienenstandbahnen befahren werden, müssen die in diesem Strecken tätigen Personen vor dem Herannahen eines Zuges gewarnt werden. Dazu ist es üblich, daß der Zug eine sogenannte Warnkatze mit sich führt, auf der akustische und/oder optische Anzeigen angeordnet sind, die von einem Generator gespeist werden, der in der Regel von einem auf der Fahrschiene mitlaufenden Rad angetrieben wird. Derartige Warnkatzen besitzen ganz erhebliche Gewichte von z. B. 250 kg. Durch eine solche Warnkatze wird nicht nur der Zug verlängert sondern auch die Transportleistung des Zuges verringert. Wird der Generator der Warnkatze von einem auf der Schiene laufenden Rad angetrieben, dann hängt die vom Generator abgegebene elektrische Leistung und damit auch die Intensität der Anzeige von der Fahrtgeschwindigkeit des Zuges ab. Das auch alles reicht häufig nicht aus, um die in der Strecke tätigen Personen, insbesondere im Bereich von Baustellen hinreichend frühzeitig und mit der notwendigen Intensität vor dem Herannahen bzw. Durchfahren eines Zuges zu warnen.In underground routes that are used by monorails or long-distance railways, the people working on these routes must be warned before a train approaches. For this purpose, it is common for the train to carry a so-called warning trolley, on which acoustic and / or visual displays are arranged, which are fed by a generator which is generally driven by a wheel running on the rail. Such warning cats have very considerable weights of z. B. 250 kg. Such a warning cat not only lengthens the train but also reduces the train's transport capacity. If the generator of the warning trolley is driven by a wheel running on the rail, then the electrical power emitted by the generator and thus also the intensity of the display depend on the speed of the train. All this is often not enough to warn the people working on the route, especially in the area of construction sites, sufficiently early and with the necessary intensity that a train is approaching or passing through.

Aufgabe der Erfindung ist es deshalb, eine Warneinrichtung für untertägige Schienenbahnen anzugeben, die den Zugbetrieb nicht belastet und die hinreichend intersive Warnsignale abgeben kann.The object of the invention is therefore to provide a warning device for underground railways that does not operate the train burdened and can give sufficiently intersive warning signals.

Diese Aufgabe wird mit einer Warneinrichtung der eingangs beschriebenen Gattung gelöst, welche gekennzeichnet ist durch wenigstens vor und/oder hinter dem Baustellenbereich stationär angeordnete Sensoren, die auf das Herannahen oder Vorbeifahren eines Zuges ansprechen, und durch eine oder mehrere im Baustellenbereich angeordnete, von den Sensoren gesteuerte Anzeigen. Die erfindungsgemäße Warneinrichtung wird unabhängig vom Zug installiert. Das hat zunächst den Vorteil, daß der Zug durch eine zusätzliche Warnkatze nicht mehr belastet wird. Folglich kann die Transportleistung des Zuges erhöht werden. Darüberhinaus ermöglicht es die stationäre Anordnung von Sensoren und Anzeigen in der Strecke dieser Geräte aus Energiequellen zu speisen, die in der Strecke angezapft werden können.This object is achieved with a warning device of the type described at the outset, which is characterized by sensors arranged stationary at least in front of and / or behind the construction site area, which respond to the approach or passing of a train, and by one or more sensors arranged in the construction site area controlled ads. The warning device according to the invention is installed independently of the train. This has the advantage that the train is no longer burdened by an additional warning cat. As a result, the transport performance of the train can be increased. In addition, the stationary arrangement of sensors and displays in the route of these devices makes it possible to feed from energy sources that can be tapped in the route.

Ist eine solche Warneinrichtung vorhanden oder installiert, dann können ohne weiteres in Baustellenbereich zusätzliche Sensoren für eine Anwesenheitsmeldung eines Zuges angeordnet werden. Damit ergibt sich die Möglichkeit, das Baustellenpersonal auch auf einen im Baustellenbereich haltenden Zug aufmerksam zu machen.If such a warning device is present or installed, additional sensors for the presence of a train can easily be arranged in the construction site area. This gives the opportunity to make the construction site personnel aware of a train stopping in the construction site area.

Vorzugsweise werden berührungslos arbeitende Sensoren eingesetzt, z.B. Sensoren, die nach dem Reflexionsprinzip arbeiten. Es können aber auch induktiv oder kapazitiv arbeitende Sensoren eingesetzt werden, wenn das die gegebenen Umstände zulassen.Non-contact sensors are preferably used, e.g. Sensors that work on the reflection principle. However, inductive or capacitive sensors can also be used if the circumstances allow.

Eine andere Möglichkeit besteht darin, als Sensoren mechanisch durch den Zug betätigbare Schalter einzusetzen.Another possibility is to use switches mechanically actuated by the train as sensors.

Zweckmäßig sollten richtungsabhängig arbeitende Sensoren eingesetzt werden, damit festgestellt werden kann, ob ein Zug in den Baustellenbereich einfährt oder diesen verläßt. Das läßt sich z.B. mit paarweise angeordneten Sensoren erreichen.It is advisable to use directional sensors so that it can be determined whether a train is entering or leaving the construction site area. This can e.g. with sensors arranged in pairs.

Wenn der betreffende Streckenabschnitt für Zugebetrieb auf mehreren Gleisen oder Zweiggleisen eingerichtet ist, empfiehlt es sich, jedem Gleis eigene Sensoren zuzuordnen, damit Fehlschaltungen weitgehend ausgeschlossen sind.If the route section in question is set up for operation on several tracks or branch tracks, it is advisable to assign sensors to each track so that faulty switching is largely excluded.

Es versteht sich, daß die Warneinrichtung außer den Sensoren und Anzeigen auch eine Steuer- und Überwachungseinrichtung aufweisen kann, die insbesondere den Funktionsablauf komplizierterer Schaltungen überwacht.It goes without saying that, in addition to the sensors and displays, the warning device can also have a control and monitoring device which, in particular, monitors the functional sequence of more complicated circuits.

Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; die einzige Figur zeigt in schematischer Darstellung ein Gleis mit Zweiggleis für eine Schienenbahn in einem untertägigen Streckenabschnitt.In the following an embodiment of the invention shown in the drawing is explained; the single figure shows a schematic representation of a track with branch track for a railroad in an underground section of the route.

Das in der Zeichnung dargestellte Gleis 1 ist beispielsweise das Gleis (Fahrschiene) einer nicht dargestellten Einschienenhängebahn. Vom Gleis 1 geht ein Zweiggleis 2 ab. Das Gleis 1 und ein Teil des Zweiggleises 2 führen durch einen Baustellenbereich B, in dem mehrere Personen tätig sind.The track 1 shown in the drawing is, for example, the track (running rail) of a monorail monorail, not shown. A branch track 2 leaves from track 1. The track 1 and part of the branch track 2 lead through a construction site area B, in which several people are active.

Vor und hinter dem Baustellenbereich B sind am Gleis 1 und auch am Zweiggleis 2 jeweils Sensoren 3,4,5 angeordnet, die das Herannahen oder Vorbeifahren eines Zuges registrieren können. Es mag sich dabei um berührungslos arbeitende Sensoren handeln, die auch - die Fahrtrichtung des betreffenden Zuges feststellen können.In front of and behind the construction site area B, sensors 3, 4, 5 are arranged on the track 1 and also on the branch track 2, which can register the approaching or passing of a train. These may be non-contact sensors that can also determine the direction of travel of the train in question.

Innerhalb des Baustellenbereiches B sind weitere Sensoren 6,7 neben dem Gleis 1 angeordnet, die ebenfalls berührungslos arbeiten und mit denen die Anwesenheit eines Zuges im Baustellenbereich B festgestellt werden kann.Within the construction site area B, further sensors 6, 7 are arranged next to the track 1, which also work without contact and with which the presence of a train in the construction site area B can be determined.

Mit den Signalen der Sensoren 3 bis 7 werden, gegebenenfalls unter Zwischenschaltung einer nicht dargestellten Steuer- und überwachungseinrichtung optische und/oder akustische Anzeigen 8,9,10,1] gesteuert, die im Baustellenbereich verteilt angeordnet sind.The signals from sensors 3 to 7 are used, optionally with the interposition of a control and monitoring device (not shown), to control optical and / or acoustic displays 8, 9, 10, 1] which are distributed in the construction site area.

Die Sensoren, die Anzeigen und die nicht dargestellte Steuer- und Überwaschungseinrichtung werden mit elektrischer Ernergie gespeist, die von in der Strecke oder im Baustellenbereich B ohnehin vorhandenen elektrischen Anschlüssen abgenommen wird.The sensors, the displays and the control and monitoring device (not shown) are supplied with electrical energy which is taken from electrical connections which are present in the route or in the construction site area B.

Die dargestellte Warneinrichtung arbeitet wie folgt: ein nicht dargestellter Zug, der sich dem Baustellenbereich B nähert und am Sensor 4 vorbeifährt, löst dabei am Sensor 4 ein Signal aus, welches die Anzeigen 8,9,10,11 im Baustellenbereich aufleuchten und/oder tönen läßt. Wenn der Zug im Baustellenbereich hält, wird seine Anwesenheit von einem oder mehreren der im Baustellenbereich B angeordneten zusätzlichen Sensoren 6,7 erfaßt, deren Signale wiederum die Anzeigen 8 bis 11 steuern, gegebenenfalls in einem anderen Rhythmus als bei einfacher Durchfahrt des Zuges. Wenn der Zug den Baustellenbereich B wieder verläßt, wobei er entweder den Sensor 4 oder den Sensor 3 oder den Sensor 5 am Zweiggleis 2 passiert werden sämtliche Anzeigen wieder gelöscht. Ähnlich funktioniert die Warneinrichtung auch, wenn der Zug am Sensor 3 vorbei in den Baustellenbereich B einfährt oder wenn der Zug über das Zweiggleis 2 und am Sensor 5 vorbei in der Baustellenbereich B einfährt.The warning device shown works as follows: a train, not shown, which approaches the construction site area B and passes the sensor 4, triggers a signal at the sensor 4 which lights up and / or sound the displays 8, 9, 10, 11 in the construction site area leaves. When the train stops in the construction site area, its presence is detected by one or more of the additional sensors 6, 7 arranged in the construction site area B, the signals of which in turn control the displays 8 to 11, possibly in a different rhythm than when the train simply passes through. When the train leaves construction site area B again, passing either sensor 4 or sensor 3 or sensor 5 on branch track 2, all displays are deleted again. The warning device also works in a similar manner if the train enters sensor 3 into construction site area B or if the train enters branch 2 and sensor 5 past construction site area B.
